Aluminium Rack  And  Pinion Actuators

Our Quifer Rack & Pinion pneumatic actuators are specifically designed for use with quarter-turn valves, sporting a wide torque range that ensures our actuators match the operational characteristics of plug, ball or butterfly valves; or any other device requiring precise and reliable 90º rotary motion.

Our pneumatic actuators are constructed of high quality material and undergo 100% pressure, leak and rotation testing before being dispatched.
